三维动态标记下髋关节活动度与下肢功能权重

Range of Hip Joint Motion and Weight of Lower Limb Function under 3D Dynamic Marker

目的探讨髋关节在下肢功能中合理的权重系数范围。方法通过LUKOtronic运动捕捉与分析系统记录健康受试者髋关节在正常状态下的下肢运动情况以及髋关节在功能位、屈曲位和伸直位三个不同位置固定时的下肢运动情况,经Fugl-Meyer下肢运动功能评定量表计算获得髋关节在上述三个不同位置固定时的下肢功能丧失程度,通过单因素方差分析和Tamhane’s T2法进行统计分析,推算髋关节合理的权重系数范围。结果髋关节在屈曲位和伸直位固定时导致的下肢功能丧失程度与功能位固定导致的下肢功能丧失程度比较,差异具有统计学意义;而屈曲位固定与伸直位固定时下肢功能丧失程度之间比较,差异无统计学意义。根据95%的置信区间计算,髋关节在下肢功能的权重系数范围为61.05%~73.34%。结论在髋关节残损功能评价中,除了确定合理的权重系数以外,还需考虑功能位与非功能位因素对下肢功能丧失程度的影响。

Objective To explore the range of reasonable weight coefficient of hip joint in lower limb function. Methods When the hip joints of healthy volunteers under normal conditions or fixed at three different positions including functional, flexed and extension positions, the movements of lower limbs were recorded by LUKOtronic motion capture and analysis system. The degree of lower limb function loss was calculated using Fugl-Meyer lower limb function assessment form when the hip joints were fixed at the aforementioned positions. One-way analysis of variance and Tamhane＇s T2 method were used to proceed statistics analysis and calculate the range of reasonable weight coefficient of hip joint.Results There were significant differences between the degree of lower limb function loss when the hip joints fixed at flexed and extension positions and at functional position. While the differences between the degree of lower limb function loss when the hip joints fixed at flexed position and extension position had no statistical significance. In 95% confidence interval, the reasonable weight coefficient of hip joint in lower limb function was between 61.05% and 73.34%. Conclusion Expect confirming the reasonable weight coefficient, the effects of functional and non-functional positions on the degree of lower limb function loss should also be considered for the assessment of hip joint function loss.
